Eighty-seven contaminants of emerging concern were analyzed in Great Lakes Caspian tern eggs. Order of concentrations in tern eggs was ΣPFSAs > ΣPFCAs ≈ ΣPBDEs » ΣNPHFRs ≈ ΣOPEs. Tern eggs contained significantly greater PFAS but lower FR levels as compared to gull eggs. Tern eggs contained extremely high concentrations of PFOS with the greatest being up to 4.7 ppm. The new PFSA, PFEtCHxS, showed a detection frequency of 100% in all analyzed eggs.
